Title: Method for forming wiring
Inventor: HASEGAWA TOSHIAKI
IPC: H01L23/52
Filed: 1990-09-12
Abstract: PURPOSE:To achieve selective growth of a high melt-point metal from an interface between an interlayer insulation film and a lower-layer wiring by forming a contact hole by overetching the interlayer insulation film. CONSTITUTION:Patterning is performed by forming a DOPOS film 11 and a WSix film 12 which are extended for example from a gate electrode along a wafer surface on an SiO2 insulation film 10 such as field oxide film and an interlayer insulation film 13 is deposited on it. Then, a resist pattern is formed by using the lithography technique and anisotropic etching is performed with this resist as a mask, thus enabling a contact hole 14 to be provided. A tungsten is allowed to grow selectively within the contact hole 14 by the CVD method. A nucleus-shaped tungsten particle 15a begins to grow at an interface between the WSix film 12 and the interlayer insulation film 13. After that, this tungsten particle 15a continues to grow as a species, thus enabling the contact hole 14 to be buried.

Title: Sucked air flow rate measuring instrument for internal combustion engine
Inventor: YONEKAWA MASAO
IPC: G01F1/68
Filed: 1989-09-18
Abstract: PURPOSE:To accurately control an air-fuel ratio and an ignition period by correcting a flow rate which is detected by an air flow rate detecting means in idling operation based on an air flow rate estimated by a by-pass air flow rate estimating means. CONSTITUTION:The air control valve M5 of a by-pass passage M4 is controlled with a duty signal from an idling rotational speed adjusting means M6. Consequently, the flow rate of sucked air passing through the passage M4 pulsates and the air control valve M5 is opened more as the load on the engine is increased in the idling operation; and the rate of the air flow rate in a total sucked air flow rate is larger and larger as the flow rate in the passage M4 is larger and larger. Therefore, the sucked air flow rate measuring instrument corrects the detected flow rate by a correcting means M10 based on the flow rate of air passing through the passage M4 which is estimated by the passing air flow rate estimating means M9 to correct the air flow rate according to the extent of the pulsation of the sucked air flow rate, thereby accurately finding the air flow rate.

Title: Magnetic card reader writer
Inventor: SASO HIROSHI
IPC: G06K19/06
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To prevent a forged card from being used by accurately detecting the forged magnetic card. SOLUTION: When the magnetic card 11 having magnetic data recorded in its 1st recording layer and high-frequency data recorded in its 2nd recording layer is used, the card reader writer 3 processes the output waveform of magnetic data from a read circuit 35 through the read coil 34B of a magnetic head 34 through Fourier transform by a fast Fourier transforming means 31A. A CPU 31, when judging that the waveform of the high-frequency data is included based on the transformation result, recognizes that the card is genuine. When the transformation result does not include the waveform of the high-frequency data, it is recognized that the card is a forged card which is not issued by a formal card issuing machine or a forged card where new data are written by a 3rd person after the data of the recording layer are erased, thereby inhibiting the card from being used.

Title: Card having true or false discriminating means
Inventor: DOMEKI NORIYOSHI
IPC: B42D15/10
Filed: 1990-09-14
Abstract: PURPOSE:To improve a forgery preventive effect while easily discriminating true or false by forming a reversible thermal layer, which cannot be detected visually at normal temperature and can be detected visually at a predetermined temperature, to at least one part of a card. CONSTITUTION:An irreversible thermal layer is composed of at least one kind of reversible type thermal ink and a thermochromic material. An electron donative substance and an electron acceptable substance mutually work in the reversible type thermal ink, and it displays a color at 50 deg.C or lower under a crystalline state. When a colored crystal is heated under the state, the electron acceptable substance dissolves, the mutual donative action of electrons is removed, and the thermal ink is made colorless at 90 deg.C or higher. On the other hand, the reversible thermochromic material is brought to a colored state at room temperature, the colored state falls along a curve 21 by heating and the transmittance of light increases, and the reversible thermochromic material is brought to a colorless state at 100-150 deg.C. Accordingly, since a reversible type thermal layer is formed to at least one part of a card, the reflection density of the layer is measured, thus discriminating true or false by a reflection density value measured.

Abstract: PURPOSE:To obtain an excellent distortion characteristic even in a frequency region in which the effect of terminal capacitance of a SAW filter is not negligible and to reduce the ripple within the band by providing a differential amplifier and the SAW filter. CONSTITUTION:An input signal at a terminal 1 is given to a base of a transistor(TR) Q3 via a capacitor C1. A base of a TR Q4 is connected to ground via a capacitor C9. Balanced outputs with same amplitude and a phase difference of 180 deg. are obtained from collectors of the TRs Q3, Q4 with the selection of R13=R14. The outputs are given to the balanced input terminals of a SAW filter 6 via capacitors C9, C10 and outputs of the balanced signals whose band is limited are obtained from terminals 7, 8. An electrode capacitor Rci as an input impedance of the SAW filter 6 is connected between the collector resistors R13, R14. As a result, the load impedance of the differential amplifier including the TRs Q3, Q4 is not decreased even in a high frequency region where the Rci is decreased and the deterioration in the distortion characteristic is prevented and the ripple characteristic within the band is improved with mismatching state for the use of the SAW filter 6.
